New report highlights fructose as a key driver of metabolic disease

Researchers emphasize fructose’s unique role in obesity, metabolic syndrome and other chronic diseases

Revealed: how male and female brain cells differ in gene activity

Variations in gene expression could help to explain why brain-disease risks differ according to sex.

Singing mice puff up air sacs to make their sweet songs

Unlike other animals, these mice use inflatable throat sacs to produce sound, not just shape it

Human echolocation works step by step

Navigating the world as a blind person sometimes involves using a cane, guide dog or wearable GPS system. For some, this toolkit includes echolocation. Producing tongue clicks and listening for echoes can be enough to gain information about nearby objects.

Snippets of hair may expose chronic stress in war refugees

Cortisol in hair may be a better indicator of chronic stress in war refugees than a commonly used questionnaire, researchers reported March 19 at the annual meeting of the American Association of Biological Anthropologists in Denver.

United Nations University and Tsinghua University launch the UNU Hub for Ethical and Responsible AI Development in Beijing

Can weight-loss pills replace injectables? What the science says

The weight-loss drugs that took the world by storm a few years ago have a drawback for anyone afraid of needles: they must be injected weekly. But scientists have been racing to perfect anti-obesity pills — which are now coming to market.

A static electricity mystery comes to the surface

Static electricity, a charge buildup caused by rubbing or touching, is a poorly understood phenomenon, despite its prevalence.

Key Alzheimer’s proteins are competing inside brain cells

New UC Riverside-led research suggests Alzheimer’s arises not simply from plaques forming in the brain, as is widely believed, but from one protein interfering with the normal job of another.

Physicists dream up ‘spacetime quasicrystals’ that could underpin the universe

Mind-bending materials called quasicrystals have an orderly structure, but without a regularly repeating pattern. They’ve been found in meteorites and the debris from the first atomic bomb test. Scientists have now discovered that they can theoretically inhabit an even stranger realm: spacetime, the blended mixture of time and space of Einstein’s special theory of relativity.

Why is math harder for some kids? Brain scans offer clues

Some kids struggle with math. Now, scientists have pinpointed some of the specific thinking processes and brain regions that might explain why math is a little harder for some than others.

Can you trust the results from gut microbiome tests? Maybe not

Seven direct-to-consumer microbiome testing companies each got three identical fecal samples but returned different results about which gut microbes were present, researchers report February 26 in Communications Biology.

Scientists design solar-responsive biochar that accelerates environmental cleanup

Researchers have developed a new strategy to engineer biochar with dramatically enhanced sunlight-driven chemical activity, opening promising pathways for environmental remediation and pollutant transformation. The findings demonstrate how combining biochar with artificially synthesized humic substances can significantly boost its ability to drive light-powered reduction reactions that influence metal cycling and contaminant transformation in natural environments.

Earth is bathed in droves of neutrinos spewed by the Milky Way’s stars

About 1,000 of the subatomic particles, born in stars other than the sun, pass through a thumbnail every second

A Greek star catalog from the dawn of astronomy, revealed

A hidden astronomical catalog has been uncovered in a particle accelerator experiment

AI-driven ultrafast spectrometer-on-a-chip: A revolution in real-time sensing

For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory instruments called spectrometers.

Global societies unite to address environmental threats to heart health

Sophia Antipolis, France – 20 January 2026. The world’s leading cardiovascular societies, the European Society of Cardiology (ESC), the American College of Cardiology (ACC), the American Heart Association and the World Heart Federation (WHF) have today issued the first ever joint statement calling for urgent action to address environmental stressors as major, yet preventable, causes of cardiovascular disease (CVD).1

A newly spotted asteroid spins faster than any of its size ever seen

PHOENIX — A newly discovered asteroid spins about as fast as a Ferris wheel. With a rotation period of just 112 seconds, it’s the new record holder for fastest-spinning asteroid wider than 500 meters. Scientists think it must be made of solid rock to avoid breaking apart.

Low-cost visible light communication system achieves stable outdoor data transmission using LEDs

Visible light communication (VLC) is attracting increasing attention as an alternative wireless technology that uses light emitted from LEDs to transmit data.

Twisted stacks of 2-D carbon act like a weird type of superconductor

A material made of three layered and rotated graphene sheets (illustrated in purple) shows evidence of unconventional superconductivity. In the material, electrons (yellow) pair up in a way that allows them to travel without resistance.

Clinical trials on AI language model use in digestive healthcare

Large language models (LLMs), such as ChatGPT, have rapidly entered healthcare, but strong clinical evidence for their real-world use remains limited. A new study published in Gastroenterology & Endoscopy provides the first overview of randomized controlled trials (RCTs) evaluating LLMs specifically in digestive diseases.

An injected gel could make drugs like Ozempic last longer

Less frequent dosing of GLP-1 drugs would be easier for patients

A new kind of telescope is set to search for mysterious fast radio bursts

Radio telescopes usually have giant dishes, but not these all-sky antenna arrays

Engineers transform dental floss into needle-free vaccine

Flossing may be good for more than getting your dentist off your back

Giant Solar Telescope Empowers Space Observation

In the remote highlands of Daocheng, a county nestled 4,700 meters above sea

First Quantum Confinement Achieved Without Physical Downsizing

Quantum confinement is a physical effect that occurs when the size of a material—usually a semiconductor or conductor—is reduced to the nanoscale thereby restricting the movement of electrons or holes.
